Abstract
Three cosmic-ray events have been detected which can be interpreted in terms of long-lived ( sec) particles with charges (± 10%) of ± 0.70, ± 0.68, and ± 0.42 respectively, and masses greater than , , and at the 90% confidence level, respectively. The probability for explaining the events in terms of previously known particles is estimated and found to be low.
